driving in December

First of all, i am grateful for all the information which has been posted on this forum!
I am going to be in Japan for 2 weeks in late December and thought it might be nice to drive up/or down the Noto Peninsula or in Hokkaido to take in some scenery, but I've been told Noto may not be so accessible now and winter Hokkaido is not car-friendly..
I went to Shimoda in the Izu Peninsula last year and wanted to find something scenic, preferably along the coastline but in another part of Japan - unfortunately I can only do the drive for 3 days.. so options might be limited.. any suggestions or ideas would be appreciated!
thanks!

. . .. . . the Rikugen Kaigan coast (northern Tohoku) and Obama Five-Lakes to Tojimbo area (Fukui), but an early winter snowstorm is possible.

A good bet for you in 3 days is rent a car in Toba and drive along the coastline of Wakayama peninsula to Kansai Airport or Osaka. There are a myriad of sightseeing attractions in this stretch, such as a riverboat ride along a gorge, a waterfall, an orange temple nearby, Shirahama resort area (with safari park if you are into that).
